Sampling Activities

    

Combined Sewer Overflow-Stormwater Outfall (CSO-SWO) Monitoring Program [September 2011]:

Combined sewers transport wastewater and stormwater runoff to sewage treatment plants. During certain storm events, excess wastewater and stormwater that cannot be treated at the plant is diverted directly to the river through combined sewer overflows (CSOs). Separated storm sewers transport only stormwater runoff; during precipitation events, storm sewers discharge to the river through storm water outfalls (SWOs). Representative CSOs and SWOs are being sampled to characterize the concentration of contaminants coming into the Lower Passaic River from these sources. The data will be used to evaluate whether CSOs and SWOs are significant sources of contaminants to the river. The work plan that details the sampling is posted in the Digital Library, under "Sampling\Passaic River".

Small Volume Chemical Water Column Monitoring Program [August 2011]:

Surface water in the Lower Passaic River and Newark Bay is being collected and analyzed for a suite of contaminants to characterize chemical concentrations in the water column. Relatively small volumes of water (about 2 liters or less per contaminant group being analyzed) are being collected under various flow conditions (routine, high and low flows) over the four seasons of the upcoming year. Stations are located throughout the 17-miles of the Lower Passaic River, around Newark Bay, and on the major tributaries of the Lower Passaic River and Newark Bay. The data will be used to evaluate risks to human health and biota from exposure to surface water and to calibrate the model that simulates fate and transport of contaminants in the river and bay. The work plan that details the sampling is posted in the Digital Library, under "Sampling\Passaic River".

Mudflat at River Mile 10.9 [Summer-Fall 2011]:

The mudflat on the east side of the river at River Mile 10.9 (Lyndhurst, NJ) is being sampled to characterize the nature and extent of contamination in the sediments, and to understand the potential for those sediments to migrate and become a source of contaminants to other areas in the river. Sediment cores, bathymetry surveys and data on local waterflow patterns are being collected. This work is described in a work plan available in the Digital Library, under "Sampling\Passaic River".

Bird Community Surveys [2010-2011]:

Four avian community surveys have been conducted on the Lower Passaic River to characterize the birds that use the river, as well as habitats where birds are observed. This information, combined with other data, will be used in the ecological risk assessment. The avian surveys were conducted in the summer 2010, fall 2010, winter 2010-11 and spring 2011. The work plan defining how the surveys are done and a report on the results of the first and second surveys are available in the Digital Library, under "Sampling\Passaic River". Reports on the results of the last two surveys will be posted in the future.

Cooperating Parties Group (CPG) Sediment Sampling Work Plan [July 2008]:

A group of 73 companies, named the CPG, has taken over implementation of the 17-mile study (Superfund program side), under EPA oversight. This Work Plan describes the first comprehensive sampling of the sediments of the 17-mile study area. Maps of the sample locations (click here), field procedures (click here) and an investigation into how PCBs move from sediment particles into water (click here) are also included. The work described in these documents is scheduled to be done in the Summer-Fall of 2008. Each of these files is very large, so please allow some time for downloading them.

Work Plan, Maps and Quality Assurance Project Plan (QAPP) [August 2005]:
This Work Plan presents a united overview of the sampling activities and other investigations being conducted for the Lower Passaic River Restoration Project. This Work Plan is a dynamic document that will be amended as the project evolves and additional work phases are planned. Individual activities presented in the Work Plan are described in more detail in their own field sampling plans, as shown below. Attachment B to the Work Plan, the Geochemical Evaluation (Step 1) is provided on the Conceptual Site Model Page of this website Also available is a Quality Assurance Project Plan (QAPP) that details the planning processes for collecting data and describes the quality assurance and quality control activities developed for this project.

Dundee Lake Sediment Coring [December 2006-January 2007]: This survey collected sediment cores from above Dundee Dam and will analyze them for a number of contaminants, including dioxins, PCBs, metals, PAHs, and pesticides. The data will be used to determine the depositional history and concentration of contaminants in the sediments above Dundee Dam. To review the QAPP amendment for this work, click here.

Hydrodynamic Survey [July 2004-July 2005]:
This survey measures how the river flows, how sediments move, and how the water's salinity and temperature change with the tides throughout the year. The survey is being done in two coordinated phases: 1) data collected in the lower 6 miles of the river are being used to help predict how sediments might be transported during the Dredging Pilot; 2) data collected in the upper 11 miles of the river are being combined with the data collected in the lower 6 miles for use in an overall effort to model how sediments and contaminants move throughout the 17-miles of the river.

To download the hydrodynamic data that was collected using instruments moored in the Lower Passaic River, click here and also click here for the data collected by Rutgers University. For further information regarding data collected by Rutgers University click here

Please consider the following data quality parameters when using the downloaded hydrodynamic data:

  • For the data collected in the lower 6 miles of the river, final positioning of the moorings differed from proposed locations. In some instances, sensor arrays were recovered several hundred meters downstream of the original deployment location. To review the final coordinates for each mooring included in the survey, click here.
  • For the data collected in the upper 11 miles of the river, users should note that the sensors, particularly the pressure sensors, were not replaced at precisely equivalent depths throughout the survey, following regular retrieval and data download/battery replacement. Care should be taken when multiple mooring results are to be compared, even from the same mooring location.
  • The acoustic doppler current profile (ADCP) data from mooring no. 1 could not be retrieved due to sensor corruption. To view/reduce any of the ADCP data, users must download the sensor manufacturer's post-processing software tools for the RBR Logger at the following link: http://www.rbr-global.com/software.htm.

Bathymetric Survey [October 2004]:
This survey measures how deep river bottom sediments are under water. The agencies will compare this year's depths to previous years' depths to show where river sediments are accumulating and where they are scouring away. Maps showing the survey results are being prepared.

Other Surveys to Characterize Physical Properties [on-going]: Throughout the project, surveys will be conducted to characterize the physical properties of the Passaic River, focusing on the candidate restoration sites in the watershed. These surveys include the bathymetric survey described above, geophysical surveys, soil investigations, cultural resource and real estate investigations, among many others. Field Sampling Plan Volume 3 describes these surveys in detail. Click here for a report of the geophysical surveys conducted in 2005.

Partner Agency Work Plans [2005-2006]:
The Partner Agencies implemented a number of surveys to collect sediment cores and river water samples and analyze them for a number of contaminants, including dioxins, PCBs, metals, PAHs, pesticides.  Field Sampling Plan Vol. 1 describes these surveys in detail (the attachments to this document are available upon request to Alice Yeh at yeh.alice@epa.gov).  The Partner Agencies also drafted Field Sampling Plan Volume 2 that describes biological sampling work (the figures for this document are available upon request to Alice Yeh at yeh.alice@epa.gov).  That sampling work was not completed, but Field Sampling Plan Volume 2 formed the basis for the biological sampling work done in 2009 described above.

Erosion Testing [May 2005]:
Sediment cores were collected from the Passaic River and eroded using two techniques. The data will help explain how sediments are transported by river flow under normal and storm conditions.
